What are the divisibility rules to find at least four factors of the number 312?
A number is a multiple of 312 if it's a multiple of 3, 8 and 13 at the same time
Is 104 a multiple of 4?
Yes, 104 is a multiple of four. You can tell by using the divisibility rules : if the last two digits of a number are divisible by four, then the whole number is divisible by four. Now lets go back, in case you don't know, divisibility is simply if a smaller number, like four, can go into a larger number, like 104, perfectly;without having to use decimals.
What is the least natural number with four distinct prime factors?

What is the least four digit number that has 2 3 5 and 7 as factors?
1050.
How do you test to see if a number is divisible by 12?
You could combine the tests for divisibility by 3 and 4. To test for divisibility by three, add all the digits together and see if they're divisible by three. If necessary, you can keep repeating the addition until you come up with a single-digit number. To test for divisibility by four, take the last two digits. If that two-digit number is divisible by four, then the whole number is. This is because any multiple of 100 is divisible by 4, so only the last two digits matter. Combined, these two tests will allow you to quickly check for divisibility by 12.
